President-elect Donald Trump reaffirmed his commitment to keeping portions of the Affordable Care Act under his administration in his first on-air interview since being elected.

In a preview clip of the interview, to air Sunday on CBS' “60 Minutes,” Trump tells reporter Lesley Stahl that he intends to include ACA provisions that cover those with pre-existing conditions and adult children who stay on their parents' plans until age 26 in his administration’s health care plan.

“It happens to be one of the strongest assets,” Trump said. “Also with the children living with their parents for an extended period, we’re going to very much try to keep that in. [It] adds cost, but it’s very much something we’re going to try and keep.”

Trump maintained that he would keep his campaign-trail promises to “repeal and replace Obamacare,” despite his apparent willingness to incorporate it into his own plan, saying that the two-step process would be seamless.

“We’re going to do it simultaneously. It’ll be just fine. That’s what I do. I do a good job,” he said. “We’re not going to have like a two-day period and we’re not going to have a two-year period where there’s nothing. It will be repealed and replaced. It’ll be great health care for much less money.”
